The invention relates to window screens and has for its principal object the provision of a reinforcing means for the corners of the frame, said reinforcing means comprising U- shaped members secured over the corners and providing housings for roller guides on the upper portion of the frame and for latching devices on the lower portion of the frame, the invention also including specific supporting 10 means for the rollers and for the latches.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings in which Figure l is a front view in elevation of a i 15 window frame showing the improved screen frame applied thereto,

Figure 2 is a fragmentary view on an enlarged scale of one side of the frame shown partly in section and showing the casing in section,

Figure 3 is a transverse sectional View on a plane indicated by the line 3-3 of Figure 1,

Figures 4, 5, 6, and 7 are sectional details on planes indicated by the lines 4.-4, 55, 6-6, and 7-7, respectively,

Figure 8 is a view in perspective of one of the roller guide members,

Figure 9 is a similar view of one of the latch members,

Figure 10 is a view in perspective of one of the reinforcing members for the lower portion of the frame, and

Figure 11 is a similar view of one of the reinforcing members for the upper portion of 5 the frame.

In the drawings similar reference charners of the frame 2 are provided with recesses 6 to receive roller members 7, and the lower corners provided with recesses 8 to re- E T FIC ceive latchmem'b'ers 9, the reinforoing'mem bers 4 and 5 forming housings for said ro-ller Y members 7 and latch members 9." The guide member's comprise rectangular frames 10 preferably formed of sheet metal and having their mbent ends 11 secured to the frame 2 spring on the rod 15 and terminally engaging the end of the'head 14 and therear wall'16'of the frame 10 to normally hold the roller in engagement with the window casing 1. 21 is a transverse pin adjacent to the extremity of rod 15 to limit the outward movement of the rod and'roller when the from the window casing. The latch member comprises a .U-shaped frame 22 that is adapted to be secured by driven f'astenin'gs to the screen frame as shrown in Figure 2 and having its side memframe is removed bers 23 and 24 provided with circular openings 25 to slidably form a latch bolt 26', 27 indicating an expansible coil spring mounted on the latch bolt and terminally engaging a pin" 28 and the side wall 24 to normally hold the latch bolt 26in projected position. The inner end of the latch bolt 26 has a laterally extending portion 28 for manual operation of the-latch bolt 26, and the base members 5 are provided with slots 29 having angular extensions 30 and 31 in which the end 28 is movable, the extension 30 of the slot 29 being provided to engage the member 28 when the bolt is in its retracted position to hold it from movement by the spring 27,

by means of driven fastenings as shown in while the angular, extension 31 is designed to receive the .member 28 when the bolt is in locked position to hold the bolt from retraction. The wall or side 24 is extended out-' wardly as shown at 32 and upwardly as shown at 33, said slots providing room for movement of the member 28 as above described.

Secured to the sides of the window casing 1 are U-sha-ped guide members 3 1 that are provided with openings 35 at different elevations to receive the latch bolt 26 tov hold the frame in lowered or adjusted raised position, said U-shaped members 34 providing tracks between the sides of which the frame 2 is slidably mounted and the rollers 18 bear against the secured wall of the guide mem- I bers as shown in Figures 2 and 4. V

What is claimed is 1. In a window screen" construction, a' rec tangular frame having recesses in its four corners, reinforcmg members for sa1d corners comprising U-shaped members having their side members secured to the opposite sides of the frame, said Ushaped members providing walls for three sides of said recesses, and the frame providing the remaining side wall, said recesses providing; housing for guide members and latches for the frame.

2. A bearing member for Window screens comprising a rectangular supporting member, a bar slidably mounted by said member and having one end polygonal in cross section and the other end reduced and circular in cross section, the member provided with openings slidably receiving the bar and corresponding in shape to the respective ends of the bar, a roller journaled invthe polygonal end of the bar,and spring means engaging the bar and normally projecting said roller.

3. A latch for window screens, comprising a U-shaped member having alined circular openings in the sides thereof and adapted to be secured to a screen frame, one of said side members having a laterally projecting flange having its extremity bent in the direction of the attached side member, a bolt slidably and rotatably mounted in said openings, spring means normallyprojecting the a bolt, means engaging one end of said bolt and cooperating therewith to provide a latch,

the other end of said bolt having a lateral extension providing means for manual movement of the bolt, and means'engaglng sa1d lateral extension to hold the bolt in adjusted positions.

In testimony whereof I afliX my signature.
